Many students wish to know how many questions to attempt in NDA. However, attempting more questions does not mean that you will get a higher score. If you answer 100 questions correctly, you will get a better score than someone who attempts 120 questions but answers 30 of them incorrectly. Hence, you should attempt questions whose answers you are confident about:
Attempt familiar questions first, including those that need very simple calculations.
Avoid spending several minutes of your time on solving just one confusing question.
Mark uncertain questions for reviewing later.
Do not let one difficult question affect your confidence.
The elimination strategy is one of the best strategies to use while attempting the paper. If you understand a question, you can rule out incorrect options to find out the correct answer by using this strategy.
Eliminate options that clearly contradict the question.
Check units, signs, and logic behind the question.
In the Mathematics paper, use approximation or substitution techniques wherever needed.
In the GAT paper, compare all options against the exact wording of the question.
If you cannot establish a reasonable basis for any option, consider leaving it unanswered.
Many students wrongly answer a question when they miss out on terms like not, incorrect, only, etc., in the question. Hence, before you mark the answer on your OMR sheet:
Read the complete question.
Identify exactly what is being asked.
Read all four options before deciding.
Match the question number in the booklet with the question number in the OMR sheet.
